binary fission
Biology
(noun)
the process whereby a cell divides asexually to produce two daughter cells
Microbiology
Examples of binary fission in the following topics:
-
Binary Fission
- Binary fission is the method by which prokaryotes produce new individuals that are genetically identical to the parent organism.
- Prokaryotes, such as bacteria, propagate by binary fission.
- Due to the relative simplicity of the prokaryotes, the cell division process, or binary fission, is a less complicated and much more rapid process than cell division in eukaryotes.
-
Prokaryotic Reproduction
- Prokaryotes reproduce asexually by binary fission; they can also exchange genetic material by transformation, transduction, and conjugation.
- Reproduction in prokaryotes is asexual and usually takes place by binary fission.
- Binary fission does not provide an opportunity for genetic recombination or genetic diversity, but prokaryotes can share genes by three other mechanisms .
- Besides binary fission, there are three other mechanisms by which prokaryotes can exchange DNA.
-
Common Bacterial Traits
- Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction .
-
Spirochaetes
- During reproduction, the spirochaete is capable of undergoing asexual reproduction via binary fission.
- The binary fission allows for production of two separate spirochaetes.
-
Generation Time
- Bacterial growth occurs by the division of one bacterium into two daughter cells in a process called binary fission.
- Bacterial growth is the division of one bacterium into two daughter cells in a process called binary fission.
- It emphasizes clonality, asexual binary division, the short development time relative to replication itself, the seemingly low death rate, the need to move from a dormant state to a reproductive state or to condition the media, and finally, the tendency of lab adapted strains to exhaust their nutrients.

African Trypanosomiasis
- ., lymph, spinal fluid), and continue to replicate by binary fission.
- In the fly's midgut, the parasites transform into procyclic trypomastigotes, multiply by binary fission, leave the midgut, and transform into epimastigotes.
- The epimastigotes reach the fly's salivary glands and continue multiplication by binary fission.The entire life cycle of the fly takes about three weeks.
-
The Cell Wall of Bacteria
- These ancestral cells reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent.
-
Nuclear Fission
- Nuclear fission is a process by which the nucleus of an atom is split into two or more smaller nuclei, known as fission products.
- Most fissions are binary fissions that produce two charged fragments.
- These nuclei are called unstable, and this instability can result in radiation and fission.
- In order to initiate fission, a high-energy neutron is directed towards a nucleus, such as 235U.
- While nuclear fission can occur without this neutron bombardment, in what would be termed spontaneous fission, this is a rare occurrence; most fission reactions, especially those utilized for energy and weaponry, occur via neutron bombardment.
-
Types of Sexual and Asexual Reproduction
- Animals may reproduce asexually through fission, budding, fragmentation, or parthenogenesis.
- Fission, also called binary fission, occurs in prokaryotic microorganisms and in some invertebrate, multi-celled organisms.
- Some unicellular eukaryotic organisms undergo binary fission by mitosis.
- Some sea anemones and some coral polyps also reproduce through fission .
- Coral polyps reproduce asexually by fission, where an organism splits into two separate organisms.
-
Damage to the Cell Wall
- A bacterial cell with a damaged cell wall cannot undergo binary fission and is thus certain to die .
